Arteries in the circulatory system are the blood vessels experiencing the highest pressure. How are the arteries adapted to experience such high pressures?
They have rigid walls which keep a constant supply of blood.
They have thick elastic walls which allow the vessels to expand and recoil.
They have valves to prevent flow backs.
They have arterioles which absorb excess blood pressure.
Blood flows through a closed circulatory system. Where in the system does the exchange of gases and nutrients occur?
Capillary Beds
Venules
Arterioles
Heart
Describe the action of one-way valves found inside the veins.
Veins are under high pressure and valves allow the overflow of excess blood from veins.
Muscles surrounding the veins allow a milking action and valves push the blood from the heart to the tissues.
Veins have elastic walls and valves provide rigidity to prevent backflow of blood due to gravity.
Veins are under low pressure and valves prevent the backflow of blood due to gravity.
Name the very thin, flattened cells lining the inner walls of capillaries.
Red blood cells
Endothelial cells
Venules
Arterioles
Which of the following statements is FALSE about veins?
Their walls are generally thinner than arteries.
They contain valves.
They are generally under low pressure.
They carry blood away from the heart.
What is the name of the circuit that travels from the heart to the lungs and back to the heart?
The pulmonary circuit
The cardiovascular circuit
The systemic circuit
The circulatory circuit
The blood in the Pulmonary Veins travels to _____.
The left atrium of the heart
The right ventricle of the heart
The right atrium of the heart
The capillary beds of the lungs
Which of the following statements is TRUE about the blood found in the Pulmonary Arteries?
The blood is low in oxygen and under relatively low pressure.
The blood is low in oxygen and under very high pressure.
The blood is on its way to the left atrium of the heart.
The blood is rich in oxygen.
Which of the following structures contains the most richly-oxygenated blood?
The right ventricle
The right atrium
The pulmonary veins
The pulmonary arteries
Which structure does the pulmonary trunk carry blood from?
The left ventricle
The left atrium
The right atrium
The right ventricle
